Trainer Dale Romans issued an upbeat bulletin after Dullahan earned a bullet for his 45.97 four-furlong breeze on Sunday at Belmont, galloping out five furlongs in 58.91. The move was quickest of 66 at the distance.

“I thought it was super,” said Romans, who trains Dullahan for Donegal Racing.

Romans compared Dullahan’s breeze to the :57 2/5 five-furlong drill he posted at Keeneland on April 8, eight days prior to his victory in the Grade 1 Blue Grass.

“When he works like that, he runs big,” said Romans. “He looked like he was galloping, and then we got back to the barn he recovered quickly. He wasn’t blowing. I think he’s ready.”

Sunday marked the first time Javier Castellano, who will ride Dullahan in the Belmont, was aboard the half-brother to Mine That Bird.

“[Castellano] loved it,” Romans reported. “He said if you hadn’t told him the time, he would have said :48 or :49.”

In the Belmont Stakes, Dullahan will attempt to avenge his third-place finish in the Kentucky Derby, in which he made a seven-wide run to finish a diminishing 1 ½ lengths behind I’ll Have Another. Dullahan skipped the Preakness to train up to the Belmont.

“I’m happy with my position,” said Romans. “I wouldn’t change places with anybody in this race.”

Romans said Dullahan will either walk or jog on Monday, then gallop into the race.
